Answer:
D.
Explanation:
8.1X10 to the power of 6 Joules.
Answer:11
Explanation: because is the number that repeted 2 times
The computation would be:moles = mass/ Molar Mass, but we are looking for the mass, so rearranging, will give us: mass = moles x MM
Q = moles x Hf
Q = (mass/MM) x Hf
mass = (Q x MM) / Hf
= (1.50-kJ x 18.0-g/mol) / 6.01-kJ/mol
=4.49 g H20 is the answer
A compound has a definite ratio of components
